Joo, Young,Lee, Pyung-Bok,Nahm, Francis Sahngun The Korean Pain Society 2011 The Korean Journal of Pain Vol.24 No.4

Vertebral compression fractures result in vertebral height loss and alter sagittal spinal alignment, which in turn can lead to increased morbidity and mortality. Acute osteoporotic vertebral compression fractures are known to increase mobility and instability of the spine. There are limited published data correlating the degree of dynamic mobility and the efficacy of kyphoplasty on vertebral compression fractures. Here we report a 73-year-old female with a severe acute osteoporotic L2 compression fracture who obtained total vertebral height restoration following kyphoplasty, with resolution of back pain.

Street dance를 통한 공간의 의미 연구

이주영 ( Lee¸ Joo-young ) 한국무용교육학회 2021 韓國舞踊敎育學會誌 Vol.32 No.3

Street dance is the popular culture based on the free action. The culture of battle, busking, jam and cypher that is the most representative culture of street dance is the popular culture which destroys the boundary of space between ordinary world and arts by pursuing post-theater and appraised by the public by introducing their own dances in front of unspecified majority audience. They are willing to create their own actions and want to be respected through self-immersion and concentration so that the street dance that is performed in the strange and uneasy circumstances can be appraised by the public. The equal and horizontal relationship are made through the dance and opportunity of being grown up by exchanging the reaction based on the dance. The space decides the space to dance and the place to stay by itself by pursuing new and strange one not as the different attempt to attract the people’s attention, grants the meaning of the shared space that shares the aesthetic experience by the actions in aspect of ‘human body’ and creates the reconceptualization of the place regarding street dance. Current performing street dance, it becomes the stage on the street. Moreover, all are the participants and observers as well in the space of the unspecified majority and the rolls of artists and audiences are converted in free and active ways. Therefore, ‘space’ forms the platform that recognizes ‘myself’ as well as provides the opportunity of knowing true ‘myself’ through free and instant actions. As the community pursues the external directionality in the space of such street dance, it can be called as the open space, anything is possible and all can happen in the open space. That is because it expresses its own presence by occupying the identity of such space regarding that street dance creates the variety of contents by coming and going the real and media worlds and the cultural phenomenon is made through new and strange playful situation as well globally today, Street dance pursues the external directionality of space thoroughly and such directionality extends the mental dimension that enables the respect and consideration as well as the sustainablity of the attitude of admitting and accepting the variety.

중앙정부와 지방정부간 관계 영향 요인에 관한 연구 : 중앙정부의 관여, 재정적 영향력, 그리고 인사교류에 관한 중앙 및 지방공무원 인식 차이 비교를 중심으로

구주영 ( Koo¸ Joo-young ) 한국지방행정연구원 2020 地方行政硏究 Vol.34 No.4

지역주민의 행정수요에 대한 양적 증가와 질적 다양화, 사회적 난제의 출현, 고령화와 인구감소 등 현재 우리나라가 직면하고 있는 문제들을 해결하기 위해서는 중앙정부와 지방정부의 관계와 협력이 정부간 권한과 책임의 문제를 넘어서, 실질적으로 지역주민의 삶의 질을 향상시키며, 지역에서 직면한 문제를 해결하는 동시에, 중앙정부와 지방정부간 편익이 증가하는 방향으로 상호간 관계가 정립될 필요가 있다. 이때, 정부간 관계는 중앙정부와 지방정부의 관계를 수직적, 수평적 측면에서 접근할 수 있는데, 본 연구에서는 정부간 관계를 중앙과 지방의 관계로 한정하였으며, 중앙정부 차원에서 지방정부에 대한 관여, 재정적 지원 그리고 인사교류가 정부간 관계와 협력관계에 미치는 영향을 분석하고, 이 과정에서 중앙과 지방공무원의 인식 차이를 비교하였다. 분석결과, 중앙정부와 지방정부간 관계와 협력을 향상시키기 위해서 중앙정부의 관여, 재정적 영향 그리고 인사교류가 필요하며, 중앙 및 지방공무원 소속 여부에 따라, 정부간 관계와 협력 관계인식이 상이하므로 중앙정부의 관여, 재정적 관계 그리고 인사교류가 전략적으로 활용될 필요가 있다는 점을 확인할 수 있었다. The purpose of this study was to examine the relationships and cooperation between central and local governments in terms of the differences in how central and local government employees perceive such inter-governmental relationships. In this study, the factors affecting inter-governmental relationships and cooperation were central participation, fiscal relationships, and personnel exchange programs. Analysis showed that central participation, fiscal relationships, and personnel exchange programs can improve relationships and cooperation between central and local governments and that central and local government employees have different perceptions of inter-governmental relationships and cooperation. Thus, central participation, fiscal relationships, and personnel exchange programs should be strategically utilized to improve relationships and cooperation between central and local governments.

Picosecond Dynamics of CN‒-Ligated Ferric Cytochrome c after Photoexcitation Using Time-resolved Vibrational Spectroscopy

Jooyoung Kim,Jaeheung Park,Salina A Chowdhury,임만호 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.12

The dynamics of the CN‒-ligated ferric cytochrome c (CytcCN) in D2O at 283 K following Q-band photoexcitation at 575 nm was observed using femtosecond time-resolved vibrational spectroscopy. The equilibrium vibrational spectrum of the CN stretching mode of CytcCN shows two overlapping bands: one main band (82%) at 2122 cm‒1 with 23 cm‒1 full width at half maximum (fwhm) and the other band (18%) at 2116 cm‒1 with 7 cm‒1 fwhm. The timeresolved spectra show bleaching of the CN fundamental mode of CytcCN and two bsorption features at lower energies.The bleach signal and both absorption features are all formed within the time resolution of the experiment (< 200 fs) and decay with a life time of 1.9 ps. One transient absorption feature, appearing immediately red to the bleach signal, results from the thermal excitation of low-frequency modes of the heme that anharmonically couple to the CN fundamental mode, thereby shifting the CN mode to lower energies. The shift of the CN mode decays with a lifetime of 2 ps, equivalent to the time scale for vibrational cooling of the low-frequency heme modes. The other transient absorption feature, which is 3.3 times weaker than the bleach signal and shifted 27 cm‒1 toward lower energies, is attributed to the CN mode in an electronically excited state where the CN bond is weakened with a lowered extinction coefficient. These observations suggest that photoexcited CytcCN mainly undergoes ultrafast radiationless relaxation, causing photo-deligation of CN‒ from CytcCN highly inefficient. As also observed in CN‒-ligated myoglobin, inefficient ligand photodissociation might be a general property of CN‒-ligated ferric hemes.

Optimal parameter design of a cleaning device for vertical glass surfaces

Jooyoung Hong,유성근,주인호,김종원,김화수,서태원 한국정밀공학회 2019 International Journal of Precision Engineering and Vol.20 No.2

Cleaning of building windows is an extremely important issue for building owners. As construction techniques are continuously being developed, many high-rise buildings are being constructed in a competitive manner. Building owners hire human workers for cleaning their façades, who are required to hang on a rope or gondola, which takes a long time and is highly dangerous. To reduce the number of accidents and replace human workers, many researchers are developing façade maintenance robots, most of which simply use a brush and water. In this study, a new cleaning device consisting of a brush, nozzle, squeegee, and suction device was developed, and the design parameters were optimized using the Taguchi method. Cleaning experiments were conducted after contaminating windows, and the degree of contamination was measured quantitatively after applying an imaging technique.
